Using a UUP Dump ISO to update Windows 11 23H2 to 25H2 is a viable method. UUP Dump provides unofficial, community-driven ISOs based on the latest Windows updates, including Insider builds or upcoming releases like 25H2.

How to Use a UUP Dump ISO to Update Windows 11 23H2 to 25H2
1. Generate the ISO:
Visit UUP Dump and select the latest Windows 11 build (e.g., 25H2 if available).
Follow the instructions to download the UUP files and build your ISO. The website typically provides a web-based guide.

2. Create Bootable Media or Mount ISO:
Burn the ISO to a USB or DVD, or mount it directly in Windows.

3. Run Setup for In-Place Upgrade:
From within your current Windows installation, open the mounted ISO and run setup.exe.
Choose "Keep personal files and apps" to upgrade without losing files/apps.
Follow the on-screen instructions to upgrade directly.

Important Tips

  • Backup your data before proceeding.
  • Make sure your hardware drivers are compatible.
  • Use a trusted source (UUP Dump) for ISO creation to avoid tampering.
  • Be aware that UUP Dump ISOs are unofficial, so they might not undergo the same testing as official Microsoft releases.
